The couple was joined by Katherine‘s mom Maria Shriver and brother Christopher Schwarzenegger as well as Chris‘ six-year-old son Jack.

The group looked tight-knit as they said their goodbyes outside of the restaurant.

A source recently explained that Jack has been a large part of the recently engaged couple’s relationship since the very beginning.

“Instead of mostly enjoying solo, romantic dates, Chris’ son from early on was a very big part of their dating life,” the source told People.

They added, “Katherine never minded that her dates with Chris many times involved a kid activity, like a matinee movie, or going to Disneyland. Katherine is like a big kid and loves doing activities with Jack. She loves that Chris is a dad.”
